Tryptic Soy Contact Agar + LT – ICR+ is designed for the determination of the total microbial aerobic and anaerobic count on dry, sanitized surfaces and personnel in Clean rooms and Isolators. It is a complex medium for cultivation and isolation of a wide range of bacteria, yeasts and molds. The formulation of the Soybean Casein-Digest medium contains a combination of casein and soy peptones supplying organic nitrogen, particularly amino acids and longer-chained peptides. The medium is supplemented with the neutralizers like lecithin and polysorbate 80 (Tween®) and pyruvate to inactivate potential residues of disinfectants on dry surfaces. In addition, ICRplus plates (plus or “+”) are supplied with a lockable lid for safe transport after sampling without the risk of losing the lid. ICRplus plates are suitable for aerobic and anaerobic incubation by turning the lid into the close position for aerobic incubation and into the vent position for anaerobic incubation.

The product can be used for sampling until the expiry date if stored upright, protected from light and properly sealed at +15 °C to +25 °C. Condensation can be prevented by avoiding quick temperature shifts and mechanical stress. The testing procedures as described on the Certificate of Analysis can be started up to the expiry date printed on the label.
